Cab-forward
The term cab forward refers to various rail and road vehicle designs that place the driver's compartment substantially farther towards the front than is common practice. Rail locomotives In steam locomotive design, a cab-forward design will typically have the driver's compartment or cab placed forward of the boiler at the very front of the engine. On a coal-fired locomotive, the fireman's station remains on the footplate behind the firebox so as to be next to the tender. On an oil-fired locomotive, the fireman's station could be (and normally is) in the forward cab. This type of design was adapted for a few locomotives throughout Europe in the first half of the 20th century, often in conjunction with an enclosed body design and/or streamlining. Visibility is greatly improved when the cab is in this position, and in tunnels it does not fill with fumes from the chimney. However, the crew's prospects in the event of a collision are worse, and if the driver and fireman are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FS Class 670
The Rete Adriatica Class 500 (Italian: ''Gruppo 500''), classified after 1905 in the Ferrovie dello Stato Italiane (FS; Italian State Railways) as Class 670 (Italian: ''Gruppo 670'') was an unorthodox and iconic cab forward 4-6-0 (2′C) steam locomotive. Design and construction The Class 670 was designed by Eng. Giuseppe Zara of the Rete Adriatica (one of the two major railway companies in Italy at the beginning of the twentieth century); its design was very unorthodox, as the boiler was reversed on the frames, so that the cab and the firebox were leading and supported by the bogie, while the cylinders were at the rear. The compound arrangement was also highly peculiar, as it was the first experiment with the Plancher compound engine: this arrangement meant that there were four cylinders, in which the two high pressure (HP) ones and the two low pressure (LP) ones were paired together respectively on the left-hand and the right-hand side of the boiler, and each pair was served b ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its Steam locomotive components, cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a Tender (rail), tender coupled to it. #Variations, Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DRG Class 05
The Deutsche Reichsbahn's Class 05 was a German class of three express passenger steam locomotives of 4-6-4 wheel arrangement in the Whyte notation, or 2C2 h3 in the UIC notation used in continental Europe. They were part of the DRG's standard locomotive ('' Einheitslokomotive'') series. Pre World War II history Since the success of the diesel high speed trains like the Flying Hamburger in the middle of the 1930s, the German locomotive industry turned to faster steam locomotives. After speed tests with a streamlined DRG Class 03 the Borsig locomotive factories produced three engines: * 05 001 as streamlined in 1935 * 05 002 as streamlined in 1935; This engine broke the world speed record in 1936 at 124.5 mph (200.4 km/h) * 05 003 as cab forward streamlined in 1937 The locomotives did regular service in FD express passenger trains, e.g. FD 23 from Hamburg to Berlin. The design speed was 175 km/h (109 mph). In 1944, the streamline plates were remov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mallard (locomotive)
LNER Class A4 4468 ''Mallard'' is a 4-6-2 ("Pacific") steam locomotive built in 1938 for operation on the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley. Its streamlined, wind tunnel tested design allowed it to haul long-distance express passenger services at high speeds. On 3 July 1938, ''Mallard'' broke the world speed record for steam locomotives at , which still stands today. While in British Railways days regular steam-hauled rail services in the UK were officially limited to a 'line speed', before the war, the A4s had to run significantly above just to keep schedule on trains such as the ''Silver Jubilee'' and '' The Coronation'', with the engines reaching 100 mph on many occasions. ''Mallard'' covered almost one and a half million miles (2.4 million km) before it was retired in 1963. The locomotive is long and weighs 165 long tons (168 tonnes, 369,600 lbs), including the tender. It is painted in LNER garter blue with r ...

Leading Wheel
The leading wheel or leading axle or pilot wheel of a steam locomotive is an unpowered wheel or axle located in front of the driving wheels. The axle or axles of the leading wheels are normally located on a leading truck. Leading wheels are used to help the locomotive negotiate curves and to support the front portion of the boiler. Overview Many leading bogies do not have simple rotational motion about a vertical pivot. Bogies with a sliding motion controlled by springs was patented by William Adams in 1865. Other designs used swing links to take the weight of the bogie with a centering action. The first use of leading wheels is commonly attributed to John B. Jervis, who employed them in his 1832 design for a locomotive with four leading wheels and two driving wheels (a type that became known as the ''Jervis''). In the Whyte system of describing locomotive wheel arrangements, his locomotive would be classified as a 4-2-0, that is to say, it had four leading wheels, two dri ...

Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets with wheels within each set linked together. Diameter Drivin ...

Adhesion Railway
An adhesion railway relies on adhesion traction to move the train, and is the most widespread and common type of railway in the world. Adhesion traction is the friction between the drive wheels and the steel rail. Since the vast majority of railways are adhesion railways, the term ''adhesion railway'' is used only when it is necessary to distinguish adhesion railways from railways moved by other means, such as by a stationary engine pulling on a funicular, cable attached to the cars or by a pinion meshing with a rack railway, rack. The friction between the wheels and rails occurs in the wheel–rail interface or contact patch. The traction force, the braking forces and the centering forces all contribute to stable running. However, running friction increases costs, due to higher fuel consumption and increased maintenance needed to address fatigue (material), fatigue damage and wear on rail heads and on the wheel rims and rail movement from traction and braking forces.

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

Tank Locomotive 'Ariel' For The Billerica And Bedford (2 Ft
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, and ...

Franco-Crosti Boiler
The Franco–Crosti boiler is a type of boiler used for steam locomotives. It was designed in the 1930s by Attilio Franco and Dr Piero Crosti. The main difference between it and conventional feedwater heaters widely used on the continent is that the Franco-Crosti boiler uses both exhaust steam and exhaust gases from the firebox. Conventional feedwater heaters only use exhaust steam. Purpose The Franco–Crosti boiler is a modification of the conventional fire tube boiler design used on most steam locomotives. Unlike conventional boilers the heat remaining in the exhaust gases is used to preheat the water supply for the main boiler using a secondary heat exchange mechanism. This mechanism, known as the ''feedwater heater'' is essentially a secondary boiler. The preheated feedwater is fed at full boiler pressure into the main boiler via clack valves. The feedwater heater is not designed to produce steam, instead raising the temperature of the feedwater. This allows the heater to ...
